How will the CW’s The Carrie Diaries, a prequel to a series based almost entirely on having and talking about sex, handle the topic in a way that both honors Sex and the Cityand follows the rules of network television?

On the series premiere, a young Carrie Bradshaw (AnnaSophia Robb) returned to high school after a summer of grieving the death of her mother. On the first day, she “meets” the new guy in school, Sebastian Kydd (Austin Butler), who was actually Carrie’s first kiss the summer before. But now that the pair is together, how long will it be before the 16-year-old virgin starts down the path to becoming the Carrie viewers fell in love with on the HBO series? Executive producer Amy B. Harris is OK taking her time.
